Healthy and efficient housing

Housing is a fundamental component of city quality of life. A high quality, efficient home is more cost effective and healthier for occupants to live in.

Following the earthquakes, dwellings have been repaired or replaced with dwellings built to modern building codes, which set the performance standards that all new building work must meet. Aspects of the building code include moisture control, energy efficiency, durability, structural stability, access, and fire safety.

Damp and mouldy housing

One of the key determinants of a healthy home is the presence of damp and mould.  Damp and mould can occur as a result of housing being insufficiently insulated from cold and damp conditions.

In 2016, just over one in five Christchurch households agreed that their home had a problem with damp or mould during the winter months. Almost two third of households (64 per cent) did not report a problem with damp or mould, disagreeing that this was a problem at their home.

Cold housing

In 2016, half of all Christchurch households reported that their house was always or often colder than they preferred, which was slightly lower than the national proportion (52 per cent). Only 8.4 per cent reported that their house was never colder than they preferred.

Repairs needed

In 2016, just under one third of Christchurch households reported that their house did not currently require any repairs and maintenance. This was lower than for the whole of New Zealand (36 per cent).

Around 61 per cent of Christchurch households reported that minor/some repairs and maintenance were needed, which was higher than for the whole of New Zealand (58 per cent). This could be due to some houses still awaiting repair following the 2010–2011 Canterbury Earthquake Sequence.

A small proportion needed immediate/extensive repairs and maintenance (6.4 per cent of Christchurch houses).

Household crowding

Household crowding has increased slightly since 2001, possibly reflecting higher housing costs and the post-earthquake temporary housing shortage.

Between 2001 and 2013, the proportion of households requiring one more bedroom increased from 2.6 per cent to 2.9 per cent of all households. Over the same period, households requiring two or more bedrooms increased from 0.4 per cent to 0.7 per cent. These figures are below the national average.

Numerically, around 4,500 households were assessed as requiring one or more bedrooms in 2013. Maori, Pacific and Asian and MELAA households are disproportionately represented in household crowding statistics.

In 2013, 28 per cent of households needing at least one more bedroom were Maori households (despite making up 11 per cent of the City's total households), 26 per cent were Asian households (9 per cent of total households), 16 per cent were Pacific households (three per cent of total households), and four per cent were MELAA households (three per cent of total households).

Domestic energy expenditure

In 2016, Canterbury households spent an average of $46 per week on household energy costs, which was 80 cents less than in 2013.

Household energy costs as a proportion of total household expenditure have been decreasing since 2010, and in 2016 comprised 3.9 per cent of total household expenditure.

In 2016, the average household weekly expenditure on private transport supplies and services was $75, which was $17 less than in 2013 ($92). In 2013, these costs made up 6.3 per cent of total weekly expenditure, compared with 8.5 per cent in 2013.

Satisfaction with Council-owned social housing units

Social housing is an important aspect of the Christchurch housing stock. The service provides essential housing needs to vulnerable people within the City. 

Christchurch City Council currently owns more than 2,200 housing units spread throughout most suburbs in Christchurch. Social housing tenancies are managed via the Ōtautahi Community Housing Trust.

The level of satisfaction with the quality of tenancy in Council social housing units has declined since the earthquakes. In 2012, 78 per cent of residents were satisfied, compared with 64 per cent in 2017.
